The BBC is reporting that BT have called for action about Internet speeds and what ISP’s offer users. Over the last few years service providers have been offering great speeds and super fast Internet and BT wants companies to offer more honesty about what users can expect to receive.

BT supplies over eight million people and have come out and said that many customers are disappointed with the speeds they get compared to what was advertised. In a survey it found that only 15% of people paying for eight megabit per second broadband actually receive those speeds.

BT have said that regulators need to agree a set of rules about how broadband speeds are sold to potential customers stating -

“The reality is we are all trying to push the technology,”

“The industry needs to join together with Ofcom to agree a set of principles as to how these messages should be communicated and advertised so that the understanding with the consumer is as accurate as it can be.”

Whilst BT offers DSL max products with a variety of different speeds up to eight megabites per second, it does tell customers (the isps) that actual speeds will vary from user to user.

Cameron Rejali, Managing Director of Products at BT Wholesale, said it is up to the ISPs how they market broadband, “but if they are marketing it badly, the market will punish them.”

BT said users need to know about the process and that there is a difference between the line speed - what the line between their home and the exchange can support - and what it describes as “throughput”, a measure of the data coming down the line during an activity such as the downloading of a video.

Only 35% of BT’s DSL Max customers are achieving an eight mbps line speed - the rest will see their speed cut by factors such as distance from the exchange, poor equipment, and interference from electrical appliances.

But none of these five million users will achieve eight mbps “throughput” because of internet congestion and other network issues that can affect the speed of the internet connection.

“The reality is if you are very far from an exchange or there are environmental factors then your speed will come down and there is not much we can do in the short-term to address that problem,” said Mr Bradshaw.

Ofcom is now currently reviewing the way broadband is marketed to consumers.

Many people become very frustrated when it comes to replacing their cell phone with all the models on offer; they now boast an ever increasing range of functions but just where does it end? So you won’t get caught in a ‘decision trap’, become educated before you make your next phone purchase; some interesting buying facts are supplied in this article.

Sometimes we delay charging as we are too busy and this often means the phone fails but leaving recharging like this isn’t a good idea. There is nothing worse than finding out your cell phone battery is no longer holding a charge for very long as you seem to be recharging it constantly and you will probably need a new one.

Whilst there are a number of methods that can help extend the life of your cell phone battery, one really easy way is to lower the brightness of the screen back light. It doesn’t normally have to be at full intensity for you to see what’s on the screen. Actually talking on the phone uses the most power when it is being operated as it is being used as a transmitter so reduce the length of calls and turn it off if you find yourself in an area with poor reception as the cell phone battery will drain itself trying to find a signal. When ever you use your cell phone; talking, playing games, listening to music, taking picture with the flash or surfing the Internet, it will drain the battery faster so limit these activities otherwise you may not be able to make that urgent call you need.

You will often find that wallpapers, ring tones and images that are downloaded automatically will have a charge even though this is not mentioned at the start so be aware. Children are usually the most likely candidates to get caught out like this so if you are buying a phone for your child try to buy a model where you can disable this function with a password.

Cell phone plans are generally available where you pay only when it is used or through a contract that supplies a pre-agreed amount of minutes per month. It really does depend on the type of user you are as infrequent users benefit from the ‘pay per use’ plans. Weigh the prices of both types of agreements before signing on the dotted line because if you plan to use your phone regularly, then a long-term contract might be worth it. Many features are specific to certain plans so you will need to think about how you intend to use the phone to have the best features you require as part of your contract.

It is always a good idea once you are happy that your plan supplies everything you need so check the small print in case there are any further costs not immediately apparent that will be payable once you have signed on the dotted line. It is now common for people with long term contracts to have an insurance warranty included which will replace their phone if it is damaged, lost or stolen. This is more common than people think and the last thing you want is to be stuck with the bill for replacement.

When buying cell phones online, be sure the phone is up-to-date and carries all the features you want. You can then visit a local store to purchase minutes or to sign up for a contract but just be sure you buy from a company you trust.

The technology of digital communication has literally revolutionized the way people are living their life now. The advent of cell phone technology has brought the distance barrier down to the lowest. Cell phones are no longer perceived as a prized possession of the well-off. It has found its way into the hands of every next person you witness around you.

With the huge of use of cellular phones, quite a few companies around the world have woken up the business potentiality of this digital device. As a result, cell phone manufactures are vying with each other to capture the most sizable segment of the cell phone consumers by offering the best cell phone services at the lowest possible price. Moreover, they are spending thousands of dollars on research and development to outdo each other in the race of offering the most advanced technology to the cell phone users.

On the flipside, the burgeoning use of cell phones around the planet has given rise to many threats that are associated with it. Starting from theft of cell phones to radiation effect, cell phones have unleashed an array of threats the cell phone users around the world must be careful about.

Following are some of the possibilities that you cell phone can be subjected to:

Theft: Swanky cell phones are an emerging fashion norm these days; without a doubt, equally rising is the number of cell phone theft cases. With high-end cell phones models being the desire of every ambitious executive, they also become the target of kleptomaniacs who can lift cell phones at the drop of a hat. Hence, the swankier your cell phone, the more vulnerable it can becomes to the possibility of being lifted. Always make sure that you don`t leave your cell phone away from you carelessly. Besides, you should immediately inform your cell phone service provider to block or suspend your account to avoid misuse of your cell phone.

Cloning: Cloning refers to the practice of illegally charging calls to someone else`s account. When it comes to Cloning, Analog cell phones are prone to be misused to a large extent. However, if you are using a Digital cell phone, you are mostly safe from this potential threat. Cloning, as a matter of fact, can drain your account. Hence, you need to be extra careful about thing factor.

Security: Since conversations through wireless devices are transmitted using radio frequencies, it is likely that anyone can eavesdrop on your private conversation using radio scanners. However, if you are using a digital wireless phone, you are less vulnerable. The reason why digital wireless conversation is secured is that its conversations are encoded and difficult for anyone to eavesdrop on.

Insurance: Insurance is the safest way to ensure that even if your cell phone is stolen, you are likely to be compensated for it. Even if you lose your phone, cell phone insurance provider will provide to cover the loss. However, the insurance services may differ from one service provider to another.

There is only one way to play video games now days and that is playing them on a HDTV. Whatever people have told you, what ever your friends, kinsfolk, or co-workers have told you, high def. is the only way to go.

Ok you might just happen to be an individual that has never seen something in HD and that is alright, your not alone. Just about everyone in the United States has heard of HD but really don’t see what it is. A easy way to explain it is that the resolution of the image is greatly improved.

Improved? One may ask, well yes that is just it. So you should go out right now and see for your self. Now back to video games on a HDTV. For starters the picture is much clearer. When it is not in high def. the picture has what looks like to be a fuzz feeling going on with it.

Now if you are one of those people that have never seen HD then you will not mention it and would have to look for it. But if you do have a HDTV and play your video games on it ordinarily you will in fact observe a considerable difference the grade of picture.

Not only that, if you were to play a video game that you play oftentimes in HD and then switched it over to standard definition it would be enough to make your self displeased. Also it is a great excuse for you to go out and buy a HD DVD player.

That way you can start buying movies and when you see an ad on TV about a film and it says also comes in HD you can go out and buy it. The only down side to buying HD movies is the increase in price of the film. You can commonly get a regular DVD at around twenty dollars, for a high definition picture you will be spending up wards to around thirty dollars.

Though that might be a lot for just one film, HD
movies come with an extremum amount of volume compared to just a average DVD. On every DVD there are just about all the extras for that movie that you possibly could want.

If you need behind the scenes or interviews with the cast of the film they are all there. I have personally only seen a couple of HD DVDs my self one being Pirates of The Caribbean: At Worlds End which was a outstanding show, but I know for a fact that all HD DVDs have all of the content I have just said.

It is kind of like a guarantee when buying a DVD player. Not only do you get an awing improvement in the caliber of the picture but you get all of the in depth reporting of the picture it self.

I would say to all gamers or movie lovers that enjoys watching TV in general and is hunting for a improved experience save yourself the painfulness of standard definition and buy a HDTV.

While going for a long trip by plane can turn you down, because the noise of the engines would make you irritated. Some frequent travelers opt for a set of earplugs which help them from the noise of the engine and make them relaxed and not tired. Some travelers also try to listen music or watch an in-flight movie, but due to the volume frequency the noise of the engine is still heard which makes them tired. If you try to listen at a higher volume then you can get rid of the noise of the engine but that can seriously affect your hearing. You would end up with fiddling with the volume button. In this case earplugs help you to get rid of the noise but now there is a more advanced technology produced i.e. noise canceling headphones.

Using headphones is very easy thing. You just have to wear the pair of noise canceling headphones and switch them on. You would be surprised as the background noise will totally disappear.

One of the main benefits of overclocking a computer is increasing the speed. As time goes by and programs are added, the speed of a computer is diminished. Even a brand new computer could always benefit from the ability to run faster. With a click of your mouse, programs will launch without much delay and while typing, the letters will appear instantly. For a slower computer, the delay would be small but noticeable especially when you are using programs or playing games.

Another benefit from overclocking is that you will see the overall performance increase. Programs will start to run more smoothly than before and loading time will be decreased. If all goes great during the overclocking process, your computer will also have less crashes and unresponsive programs.

With the benefits of having the speed and performance increased within your system, there is yet another benefit that particularly gamers will enjoy.

When you overclock your system, you will also be effecting the video cards. These cards are what projects the graphics to your screen. For gamers, this is a major benefit since it will make the game’s graphics transform smoothly and will increase the frame rate. System lag that often angers gamers will be diminished and the best gaming experience will be achievable.

When talking about the benefits of overclocking a computer, we must mention the financial benefit. This is probably one of the main reasons people select to go this route with updating their machine. Instead of purchasing new components such as a faster processor or more RAM, a person can easily change the settings to the components and make them function at their maximum level with little or no cost associated. Depending on your current components and their settings, you can sometimes even overclock the component to a higher speed than the upgrades currently sold in stores. This is a good way to get tomorrow’s technology today.

But when talking about the benefits of overclocking a computer, we must mention the risks as well. One of the main risks associated with overclocking your computer is overheating. Since overclocking means that you will be running the components at a much higher rate than anticipated, the cooling system installed inside the computer cannot manage the higher temperatures. This leads to overheating and can cause serious damage to your system.

Another risk that is associated with overclocking is instability within your system. It is possible that overclocking can actually shut down certain components and make them stop working. One example is the sound cards. After overclocking, your sound cards may stop functioning. Also, you may see an increase in computer crashes and programs going unresponsive.

The number one rule with overclocking your computer is that if you are not willing to risk losing your computer to severe damage, don’t overclock. Anytime you alter the settings of your computer, you are taking a risk and that risk may end up being fatal to your computer.

In review, even though there is a lot of risks involved with overclocking a computer, the benefits easily make up for them. Being able to take a computer and alter the configuration to a point where your system is working at it’s maximum potential provides a great feeling of accomplishment and can boost the ego of a person within seconds.

Recent craze towards multifunctional or all-in-one printer is because these can save valuable space, convenient to do several jobs and are less costly.

A multifunctional printer is capable of doing various tasks, namely printing, photocopying, scanning, etc. Sometimes these printers can also be used as a fax machine, and you can take direct photo-prints from your digital camera.

It is important to know a few points before selecting a multifunctional printer.

The type of Printer: The two main types of printers in vogue are inkjet and laser printer. Both these printers produce high quality of printing. Inkjet printers use magnetized plated which directs ink onto sheets of paper in desired style. Normally using two cartridges, one for color and the other for black and white, the printout quality matches with laser printer. This is less costly and portable; the only disadvantage being it is much slower in comparison to laser printer.

Laser printer operates by sending a laser beam producing an image on the drum. Also known as page printers, the laser printers are much faster as the entire page is printed here in one going. Though expensive, these types of printers produce high quality printing at high speed with unlimited variety of fonts.

It is important to check the resolution of the printer. Normally higher the resolution, the better is the print quality.

Compatibility of the printer: Selection for the printer should also consider the type of operating system the printer can work with. There are printers which can work with multi-systems like Windows, Linux, Mackintosh, etc.

Scanning: By scanning, graphics and text can be directly transferred to and stored in a computer and printed as per your need. Normal multifunctional computers will have a 600 dpi resolution. In case of a photo printer the resolution may be higher. The color depth capacity of a scanner is important factor to be considered also. The greater the bit depth, the greater is the resolution and more colors can be represented.

Scanners normally come as flatbed or sheet-fed. Flatbed scanners are more versatile as they can scan a range of documents irrespective of their thickness whereas in a sheet-fed scanner the documents are scanned one sheet at a time and the documents need to be detached from the magazine or book for scanning. Scanners are normally sold with a twain driver which can be easily installed in any computer and can work seamlessly with other applications.

Copier: In comparison to analog machines, digital copiers have much larger zoom range for reducing as well as enlarging. The speed and resolution of the copier is generally the same as that of the printer.

Faxing: The easy way to transmit documents over phone line is faxing. The majority of these machines transmit between 14.4 to 33.6 kbps speeds. This means 6 to 10 seconds and 3 seconds respectively to transmit data per page. Normally 512 kilobytes of memory in a fax machine can hold about 20 to 25 pages of incoming and outgoing pages without relying on paper. The speed dial indicates how many fax numbers can be stored in the memory of the machine.

Optional items such as automatic paper feeder, extra paper trays and enhanced photo printing capability printers are available also. In case of automatic paper feeder, you don`t have to wait and feed manually for copying and scanning more than one sheet. Optional paper trays can add up 500 pages to the total capacity. Enhanced photo printing capability printers have high resolution capability, four to six cartridges and also provide a direct connection for downloading photo from your camera. Also it allows you to view the picture before printing.

The concept of xbox 360 was conceived by Microsoft in early 2003 and conceptualized in co-operation with IBM, ATI and SIS. This is a second video game console and the system allows the players to download Arcade games, demos, trailers, TV shows and movies.

The system was launched in Nov 2005 in three major regions - Europe, Japan and USA. The demand was stupendous and was sold out completely within a short span of its release. The gaming console competes with Sony Playstation 3 and Nintendo`s WII as part of seventh generation video game console.

There are three versions of Xbox 360: Arcade, Premium and Elite. Each version is backed by its own set of features, accessories and technology like wireless controller, re-chargable battery case, snazzy face plates incase the standard plain surface becomes too boring. Generally all three include hybrid, composite and component cable, a detachable 20GB hard disc drive which comes with game demos, video clips, and a free Live Arcade game.

Initially it started with the code name Xenon motherboard and subsequently re-engineered to Zephyr.The latest upgradation is a Falcon motherboard with an improved GPU heat sink. Right now the production unit is working on the next hardware refresh - GPU + CPU on the same BGA package.

The Xbox live arcade is a service that offers much more than simply downloading video games! The console actually throws up new original games, such as Assault Heroes other than the previous ones like MS Pac-Man.The Xbox video market place is an exclusive video store which can be assessed through the console. It allows the users to view HD TV Shows and Movies.The system also supports audio playback where the users may play back their own music with an interactive visual synthesizer. Pictures and slideshows can also be displayed with various transition effects by this system. These features make the Xbox a favorite of adults too along with the kids!

It is also interesting to note in this context that for a new game designer it is highly recommended that you download XNA Game Studio Express; it is an exclusive game which has been designed for easy creation of games for both Xbox 360 and windows. For developing Xbox 360 game you have to subscribe to the Creators Club apart from having Xbox 360 which has a hard drive.

In UK, the gaming console has been enabled to display BT vision, video content.The lastest video game Burnout 3 is available and till date Halo 3 is Xbox`s latest best selling game.

Xbox 360 was launched to capture the market before the arrival of Sony Playstation 3. This premature market entry had left some flaws in the hardware system undetected thereby earning itself negative publicity. However, newer designs have been introduced, and Microsoft has installed new heat sink to reduce overheating which ensures that the game console unit will last many years. Technically speaking, keeping the gaming system cool may lead to a longer lifespan of the gadget. Along with this, Microsoft has also extended the warranty period to three years in the Xbox gaming console.

Just in case you’ve been reading around and researching the many terms and topics that concern surround sound and the many surround sound systems on the market today, I thought it might be a good idea to explain some of the terminology that is floating around. First of all there are many initials names and numbers floating around when it comes to surround sound technology and equipment, it’s no wonder that many of us mere mortal consumers are more than a little confused by it all. Hopefully the information you find below will prove helpful as you weave through the wired jungles of modern sound technology.

The first and probably most common thing you will see in these circles is Dolby Digital. While there are many complicated definitions of this term the one that will matter most to you, as a consumer is that right now it is the leading format on the market when it comes to processing the digital data that your system will need to process. There are better brands such as DTS when it comes to musical sound for this function but the vast majority of television broadcasts and DVDs are optimized for Dolby.

Speaking of DTS, at the moment they are Dolby’s primary competition. While most items you find on the market such as DVDs are viewable in both DTS and Dolby you need to make sure that they system you purchase whether Dolby or DTS can read both formats for those times when your favorite flick just might not be enhanced for both.

Now perhaps the most confusing of terms when it comes to surround sound systems would be 5.1. It looks so innocent just sitting there but most people are ready to pull out their hair when they realize that it really stands for a system that includes 6 speakers rather than five. The “.1″ in the name refers to the frequency of the subwoofer (or Low Frequency Effects-LFE), which is .1. Despite the existence of ‘better’ systems on the market today, most movies are optimized for this particular set up so this will be of the most value to you with the current products on the market rather than spending more for systems that the DVD makes haven’t yet caught up with.

DTS ES refers to a format commonly referred to as 6.1. In this format there is one additional speaker moved to the center rear of the configuration and the two-rear left and right speakers are moved forward. And THX EX 7.1 is what happens when you add yet another speaker. There aren’t too many films at the moment that use this particular format some notable exceptions would be the Star Wars movies. This means that movies haven’t really caught up to the technology of either of these systems but they are on the market and some people simply must have them. I recommend going with a superior 5.1 channel surround sound system for the time being and adding speakers when there are more reasons to do so.

This list is by no means exhaustive but will give you a basic overview of the information that is relevant to you as you look into the various surround sound systems on the market today. You shouldn’t have to weed through volumes of confusing terminology in order to find out that the system you are interested in actually has 6 speakers rather than 5. My hope is that you can go in armed with basic knowledge that will help you make an informed buying decision.

In the world of music the latest entry has been the electronic keyboard. There are global manufacturers of connected software. Electronic technology has been incorporated in synthesizers, portable keyboards, digital pianos, home organs, sound modules, sequencers, drum machines and the like. There are keyboard controllers for classical and theatre organs as well as keyboard communications systems.

Whether in the classroom or home it is fun and easy to churn out music with the help of electronic keyboards. The electronic keyboard can be any one of many things - organ, piano, synthesizer or sampler. Most the electronic keyboards can be linked to the computer for experiencing the feel of real multimedia.

The digital piano combines in it the sound of acoustic piano with the fine control and expediency of an electronic device. This is done by playing reverse digital recordings or samples letting out different sounds as the player presses various notes. Like the ordinary piano this electronic model responds to the touch of the musician increasing or decreasing in volume. There is also a sustain pedal.

Some electronic keyboards are weighted so that player gets the same feel as that of an acoustic piano. The bonus point is that digital pianos are incredibly cheaper when compared to their senior cousins. These occupy less space and is minus the botheration of tuning. By using headphones it is possible to practice late at night without bothering the family and neighbours. Some sophisticated models include disk drives that allow for orchestral accompaniments and even recordings.

Electronic keyboards in organs imitate the sounds of the conventional pipe, reed and tone-wheel organs. Here again the size is fraction that of the senior organ and the price is modest - to say the least.

Electronic keyboards reach their crescendo of success in synthesizers and samplers. There are many types of synthesizers - facilities for playing back, recordings and creating exotic sounds with fine sensitive controls. There are voluminous libraries of pre-programmed sounds for the asking. Most of the synthesizers and samplers are termed multiimbral. This means playing back of many sounds simultaneously.

Another name to be acquainted with in the modern age of electronic music is MIDI or Musical Instrument Digital Interface. It is a kind of standard language in the music world that allows electronic keyboards to be inter-connected and also to be linked to the computer. Music softwares are a must for students of harmony and composition.

Portable electronic keyboards are compact, light and easy to carry. Possessing one is real cool fun. The speakers are built in and thus no external ones are required. These are chameleons of the music world and can change its character bringing out sounds of a dozen instruments at the wish of the player - piano, organ and even drums.

The market of electronic keyboards is growing very fast. Manufacturers have responded with a mixture of keyboard products. The primary has been promotion of electronic keyboard through publication and advertising enabling the public to know about it. A target has been set for introducing this new contrivance amongst music educators of music technology in major universities across US. Setting up websites for this purpose of enlightening people about electronic keyboards has also been a major step forward.

An important part of music education is music technology as can be seen the world over in television and film productions as well as the Internet. The learning and application of electronic keyboards has become relatively easy and the impact is more powerful than before. In the age of electronics changes on the musical front too are happening overnight. Thus updating is an important part of publications.

That digital cameras have brought about a sea change in the world of photography is undeniable. How one captures, prints and stores photo prints has been revolutionized. We no longer need to have loads of patience to wait for the photographer to slowly develop, print and deliver the photos in his sweet time. A tiny bit of carelessness and you would stand to lose the entire film roll.

Barely a decade ago, we would have to buy and develop a roll of film in order to snap a few photos. The number of pictures one could click was limited by the length of the film and if you wanted to do some serious photography you would need to carry a sack load of films and batteries.

You may also consider a digital camera to be a computer accessory since you can easily download photos from your camera to your PC and then take their printouts as and when you need. You may also send these photos to people as emails.

Finding the right digital camera is tough. You have to study them thoroughly. You must be sure of what you require, what you need to use to get that and what is being sold in the market. You must possess a thorough knowledge of various accessories of the it like lenses, tripods, filters and external flashes if you wish to operate like a true professional.

Digital cameras are capable of capturing sound bytes and video photography besides taking stills. For this reason, the shops stock numerous kinds of digital cameras, for example, there are video cameras or modular digital cameras that are meant for professionals. There are also certain varieties that are multifunctional.

Numerous kinds of digital cameras are found in shops and every one of them is different from the rest. The inbuilt features of the cameras decide the price tags so it will not be tough to take your pick if you are limited by your budget. However, if your pocket is not a constraint then you need to be more selective of what you buy.

Incase you purchase a camera with advanced features that you wont require, you are being wasteful, just as is the case if you buy one that doesn`t have all the attributes that you need. Whatever the case, the resolution of the camera is of cardinal importance because if it doesn`t match your requirements then it would be a total waste in terms of processing power, space for storage as well as money. Earlier on, only a resolution of 1 mega pixel was available but now resolutions up to 10 mega pixels are available and this renders excellent picture quality.

It is a folly to think that the higher the picture resolution, the better are the chances of good photo quality. If your objective is to take snaps for use on the computer, such as for web posting, or emailing, a lower resolution picture will serve the purpose quite well, as will, a low capacity memory card. All the functions of a digital camera can be executed just as well with less memory.

Software like Corel paint and Photoshop help you to bring about any number of changes in the photos you click. You could alter or modify the backdrop or make loads of other needed changes.

Digital camera could require either A size batteries or rechargeable varieties. It could be connected to your computer through bluetooth, USB or firewire ports.

The world is fast waking up to the various uses of the digital camera and the days of developing negatives are in fact becoming history. The instant gratification of seeing before your eyes the snap you clicked the previous moment, and the unmatched convenience of being able to edit the faults, make it an unrivalled choice of the next generation of photographers.

Laser Printers are commonly used printers that are known for its rapid printing abilities. The other marked feature of a laser printer is the high quality text and graphics printing. It works basically on the principle of xerographic printing process. However, it is different from the analog photocopying machines in which the image produced is the result of direct scan of a laser beam on the photoreceptor of the printer.

Using a laser printer has a number of advantages over any other types of printers available. The speed of a laser printer varies from one model to another as it depends on a number of factors like the graphic intensity required in processing the job and others. The latest models of laser printers can print more than 200 single color pages in one minute, which is more than 12 thousand pages in an hour! The color laser printers are relatively slower, but even they can print at more than 100 pages per minute. The high speed laser printers are generally used for printing of mass mailings like utility or credit card bills etc.

The cost incurred in using the laser printing technology is dependent on more than one feature such as the cost of the toner, paper, once in a while replacement of the drum, and change required in other consumable parts of the printer like transfer assembly and the fuser assembly. Laser printers having drums made of soft plastic can be costlier in the long run than one can comprehend; its high overall cost becomes apparent only when the printer requires a drum replacement.

Another feature in the family of laser printers is the duplexing model. This allows printing on both sides of a paper without the need to remove the paper at all. This technology can cut paper cost directly into half and also lessen the filling volumes. Formerly, the duplexing technology was available only on the high-end laser printers. However, now they can be seen on a number of mid-range office laser printers. Although, the duplexing technology can reduce the printing speed to some extent as the paper path length increases.

The dot-matrix and inkjet printers take the incoming spooled data for the printer and directly print that on the paper making it a slow process which can stop as soon as the printer is waiting for more data. On the other hand, a laser printer cannot work this way, the reason being the large amount of data required to output to the printer in a continuous fashion. The printer cannot wait for data arrival and if that happens, there can be gaps and misalignment on the page.

To take care of the above problem, a printer buffer is used. The data is built up and kept in the large printer buffer that is generally present in the printer. This data bank is large enough to account for every single dot that can be printed on a page. However, this requirement of storing the dots in the memory before printing can begin has limited the printing capability of laser printers to small size like A4 or A3. Most laser printer cannot print long banners as there is no memory to hold that amount of data.

The printing takes place in seven steps. A Raster Image Processor scans the entire page line by line and stores a bitmap of the page in the raster memory. The drum is then charged negatively and the bitmap is written on the photosensitive drum using a laser beam whose functionality is dependent on the bitmap image. The charged toner particles are charged negatively and wherever the laser has not discharged the drum, the charges will repel and printing won`t take place, hence creating the required print out. The toner contains a plastic powder that is attracted to the parts where the laser beam hit and in the end the plastic powder is fused at 200 degree Celsius to bond the ink with the paper.

Let me take the minute to explain what happened to us when we tried to hook up a HDTV antenna so you won’t have to waste your time doing the similar thing. First of all our entire family had always craved a HDTV. This was a chore within it’s self.

There must be 100 variant brands and types to choose from! So we did finally acquire one that we all agreed upon. After we had set up the TV we learned that we also had to acquire a HDTV antenna to be able to watch our local channels broadcasted in HD.

Our first antenna we tried was purchased at the identical spot as our TV. After we built it together in the garage we carried it inside and up the stairs to the 2nd story window. We raised it out the window and put the 17 yr old on the roof with the antenna.

We utilised walkie talkies to interact between the roof and the family room with the tv. His job was to turn the antenna in littler increments till the signal came in. The problem was we could only get 2 channels at a time coming in unobstructed but never could we get all the channels coming in at one time.

So we brought the antenna in, carried it to the garage, dissembled it and took it back to buy a bigger one and go through the entire activity again. Once more on top of the roof with the 17 yr old. Twisting and turning and all the while in a rainfall storm.

It wasn’t that bad but still raining all the same. This went on for virtually a total of 4 nights in the month of Dec during the cold and precipitation. We could never get this HDTV antenna to work so we eventually gave up.

We brought the big monster antenna in again dissembled it and put it back in the car to return. I was cheerful it didn’t work because it looked horrendous up there on the roof. It stuck out like a unhealthy thumb.

Then we did some research on the internet and found an antenna that claimed to do everything we needed and the good part was it was cheaper and way way smaller.
Actually in wasn’t no bigger than the size of a cake sheet. So we purchased the HDTV antenna and brought it home.

No assembly required and we put the 17yr old back on the roof with the walkie talkies again and this time we had a communication before we even tried to alter the antenna. It was implausible.. we found all the channels reaching in crystal clear without even trying to set the antenna in the perfect “sweet” spot that we were use to setting with the previous other two.

Just by putting it on the roof and pointing it in the generalised direction where the stations were located was all that was needed! Apparently this HDTV antenna was a much higher quality antenna. If I would have known this 5 days before,

I could have saved all those evenings, the poor kid on the roof and the aggrevation it took for our family to finally bask HDTV!

Internet connection speeds determine how fast the voice packets can be transmitted, computer processor speeds determine how fast the packets can be compressed and uncompressed, the choice of codecs used for the compression also take a part in the general quality of the service. As a rule of thumb the faster the connection and the fastest the computer (together with good compression codecs from the VoIP company) will make up for a service that is generally regarded as acceptable.

Overall, VoIP is a great low cost alternative for communication. VoIP are not just a fab that is going to go away. Its not just for kids to talk to their friends on their PCs.
